| titleOfInvention | Zoom lens and projection type display device for projection |
| abstract | For the projection among the zoom lens, make numerical aperture invariant in whole change is doubly regional, in addition, reduce total length, the lens diameter of the battery of lens of enlarged side. Zoom lens has for the projection: the 1st battery of lens (G1), its configuration be in the most enlarged side, fixed and have a positive refractive power when becoming times, at least two are moved battery of lenss (G2-G4), and its configuration is than the 1st battery of lens (G1) the position by dwindling the side more, move when change times, and opening diaphragm (St), its configuration adjacent removal battery of lens each other, or one move the battery of lens in, the projection uses zoom lens's numerical aperture to set for to invariant in whole change is doubly regional. |
